For adhesion and printing on plastic films, Grinp atmospheric plasma technology provides a
stronger and permanent corona effect. This is because the bond between the substrate (plastic
film) and the material applied to the plastic film is stronger, and the printability is higher. Since
the treatment is permanent, films can be treated just once and stocked. plasma treatment, Plastic films, atmospheric plasma, greenhouse plastic, sterilizing effect
The economic advantages of Grinp plasma treatment are significant when compared to corona or
other discontinuous plasma treatments, because of single treatment processes and elimination of
Plasma treatment also guarantees a much higher flexibility in terms of production planning, given
the possibility to stock treated films for a variety of applications over extended periods of time.
This is an additional element of cost reduction and assures shorter reaction times to market
Plasma treatment also has a sterilizing effect on any textile or flexible plastic surface.
Concerning food packaging films, Grinp plasma treatment greatly improves bonding capacity on a
variety of polymeric substrates which reduces the overall cost of manufacturing of multi-layer
plastic films (MLPF).
Grinp plasma treatment may be used to replace “tie layers” of chemical adhesives in MLPF thanks
to its powerful grafting effects, thereby reducing the structural complexity and facilitating post-
Where the outer layers of MLPF include printed graphics, Grinp plasma greatly improves the
At the same time, Grinp is now developing a new technology that creates oxygen-barrier effect
with the scope of replacing a number of barrier materials from MLPF, in compliance to EU
Another area where Grinp atmospheric plasma can impact significantly is in the treatment of the
inner surface of greenhouse plastic films. When humidity and temperature levels between the
inside and outside of a greenhouse vary significantly, condensation forms and water droplets drip
down on the plants, altering quality and growth schemes. Condensation also reduces light
transmission by up to 30%.
To prevent these problems, anti-fog chemical treatments are applied to the inner surfaces of
greenhouse plastic films. Grinp atmospheric plasma treatments eliminate chemical usage by
conferring anti-drip properties to the film which cause the water drops to flatten and slide into the
gutters without dripping on the foliage. Overall costs are lowered, both for the treatment of the
film and for the better quality of the plants. plasma treatment plastic film
Grinp’s new plasma machine is also ideal for the treatment and preparation of paper for digital
printing and imaging.
Details of PLAfilm machine:
1. Maximum working width = 1.80 meters (width of the plastic roll)
2. Maximum ext. diameter = 0.5 meters (diameter of the roll)
3. At this stage, we recommend testing non-elastic films.
4. The speed of the industrial machine will vary from 35 to 50 meters/minute. The trials on the
sampling machine will be conducted at lower speeds but perfectly simulating the industrial
process. plasma treatment plastic film
